Disclosed is a polymer comprising a block chain A composed of a random copolymer containing the repeating units (I) and (II) shown below and a block chain B containing the repeating unit (III) shown below in the order of B, A, B. Also disclosed are a crosslinked polymer obtained by a reaction between the polymer and a crosslinking agent, a composition for solid polymer electrolytes containing the polymer and an electrolyte salt, a solid polymer electrolyte and an adhesive composition.(In the above formulae, R1-R3, R6, R8, R10-R12 respectively represent a hydrogen atom or a hydrocarbon group having 1-10 carbon atoms; R4a and R 4b respectively represent a hydrogen atom or a methyl group; R 5 represents a hydrogen atom, a hydrocarbon group or the like; m represents an integer of 1-100; R7 represents a hydrogen atom, a hydrocarbon group having 1-10 carbon atoms, a hydroxyl group or the like; R9 represents a hydroxyl group, a carboxyl group, an epoxy group or the like; and R13 represents an aryl group or a heteroaryl group.)
